I just did a "Aptitude GUI" testing upgrade (aptitude -R -t stretch); Then I used command line: aptitude search -F"%p; %v; %V; %d" -t sid '?installed(?maintainer(debian-qt- kde))'|egrep 5.7|egrep '5.6|5.7.0'|less -i (goal here is empty output) to see what packages I should also upgrade from sid (Which I did after recommendations I've seen on this list); which I've upgraded using the same GUI way (aptitude -R -t sid). I had one glitch with "qml-module-qtmultimedia (5.6.1-2 and others)".
After reboot I can't see anything unusual. Chris
